.i o all whom it may concern:

Be it known that i citizen of the United States, residing at lll struction Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in a Balile Brick, ol which the following is a specification. A

This invention relates tov furnace conand more particularly to the bricks used in conjunction therewith whereby a circulation of lair maybe passed through the bricks so as to prevent cli'nkers 'becomino stuckto the brick as is now commonlyt e case. It often happens in removing clinkers from furnaces that they become so hardened to the bricks thereof that it is quite a common occurrence to break the'bricks in an endeavor to sepa-rate the clinkers therefrom. I have found by the use of the bric-ks about to described that this can be easily overcome bypassing a circulation of air through the bricks an keeping them at a comparatively low temperature so as to prevent their burning.I

In the drawingz Figure l is a sectional view taken lonritudinally through a furnace showing my improved bricks in position,

F igure 2 ils a section rtaken 2-2 of Figure l, c

Figure Ellis a perspective view of one of the l'iricks, Iy

Figure 4; is a top plan View thereof, and Figure 5 is a bottom pla-n view thereof. Reterring'to the drawing in "detail it will be seen that the Afurnace illustrated in Figure l consists of' the usual bottom and top having the end walls l and 2, the latter of which is usually'called a bridge wall. grate 2:3 is shown extending longitudinally of the furnace intermediate its top and `bot tori? lwalls as is usually the case so Ias to iorm the box and the ash pit. My iinproved bricks 4 form the side walls of the furnace. By referring especially to Fig/,- ures 3 to' 5 inclusive it will be seen that each 'brick 4 consists of a body having a rib 5 at one end 'and a groove 6 at its other end so that the bricks may be interlocked is usuali the case. No novelty is clain'ied for this eature ot thebricks but ot course some such locking means yis very desirable. A .longitudinally extending channel 6 is provided in the top edge of each brick while a plurality of transversely extending chanon the line I, FRANK H. Warm, a

nels 7 are provided in the bottom edge of each brick. The channel 6 extends from end to end of the brick whereas the transverse channel 7 extends from one side of the brick and terminatesr a distance from the other side as is Shown clearly in Figure 5.

The transverse channels 7 are in communit cation with the longitudinally extending channel 6 by means of a plurality of conduits 8 as is shown to advantage in Figure 2. There may be anyv the channels 7 and conduits 8 and of course preferred number of the same `'number of conduits 8 will be provided as there'are channels 7 and their number will necessarily vary 1n accordance with the size of the bricks which it is desired to l construct.

These bricks 4 are arranged asshown in Figure 1 and form the side walls of the fur: nace. They are situated so that the transverse channels 7 are positioned below the grate 3 and the channels 6 Iare in alignment 'with each other and form la .continuous channel -which communicates with a channel 9 provided in the bridge wall 2 and in communication with any suitable outlet 1,0.v Thus there will be a continuous currentxof air passing from the ash pit of the furnace through the transverse channel 7, conduits 8, channel 6', 'channel 9, and vfinally to the outlet l0. This current of air will suiiciently cool the bricks so as to preventthem from becoming burnt and thus it will not be possible for clinkers to stick orotherwise fasten themselves furnace as is now commonly the case.

I Obviously, the invention is not limited and restricted' to the precise and exact details of construction as illustrated and d escribed,` because it 'is susceptible of avariety of' embodiments, and many minor mechanical changes may be made .in such preferred incorporation of the invention wit-hout departing from the substance or essence of the invention and without the sacrifice ol any of its substantial benefits and advantages.
